2. According to Shu Wei, during the Three Kingdoms period, when Cao Pi proclaimed himself emperor on behalf of Han Dynasty, there was a copper hot pot, but it was not popular at that time. In the Northern and Southern Dynasties, people used hot pot to rinse pork, cattle, sheep, chicken, fish and other meat. Later, with the increasingly developed economy and culture and the further development of cooking technology in China, various hot pots appeared one after another. In the Northern Song Dynasty, there were hot pots in the pubs in Kaifeng, Bianjing, in winter. By the time of the Qing Dynasty, hot pot had become a winter delicacy of the court. By the end of the Qing Dynasty and the beginning of the Republic of China, dozens of different hot pots had been formed all over the country, each with its own characteristics. During the Muromachi period in Japan, hot pot was introduced to Japan from China on 1338. Japan calls hot pot "すきやき", also called "hoe burning".
